Avtron HS25A Optical Rotary Incremental Encoder

HS25A encoders fit shafts from 3/8" to 3/4" easily, using a durable shaft insert. The shaft insert (3/8" to 5/8") [6 to 16mm] also provides isolation from motor shaft currents, while permitting case grounding to meet NEC requirements.

Avtron encoders have superior shaft seals and bearings that stay sealed to keep contaminants out, through temperature cycling and liquid sprays. HS25A encoder seals are protected by mechanical barriers to prevent flexing or failure, and Avtron’s superior bearings feature synthetic lubricants for even longer life.
